Well,I am still not sure!!!
1amu=(1/Avagadro no) gm(Since by def. 1amu=1/12 of mass of C-12)

Therefore,1amu of any substance should have the same mass i.e wC-12=wC-14.Why not!!

well i suppose uttara is right

according to the calculation

FACT: I dont have brains

so if we consider practically C 14 must hav more mass...isnt it??

Where do you find my explanation wrong???
